They rounded up a bunch of high human capital people, sent them off to (maybe) nonrandom remote locations but in *random proportions* - then come back ~65 years later to find higher education, higher wages and more economic development 🔥

Enemies of the people were the educated elite, targeted by the Soviet authorities for they posed a threat to the propaganda-dependent regime. Along with millions of other non-political criminals, they were sent to forced labor camps scattered across the Soviet Union, the Gulag. https://t.co/fo5lf7Zmvo

Earnings penalties that come with mental illness:
Depression: -34% $
BD: -38% $
Schizophrenia: -74% $
But, treatments for mental illness help eliminate a significant portion of these $$$ penalties.

Do elite schools improve students' outcomes?
Students who just make it in elite schools in Chicago do not have better results later on, relative to students who just miss out on entry. Those from disadvantaged backgrounds even get *worse* results.

New paper on payments anonymity: papers.ssrn.com/sol3/papers.cf…
Anonymous digital cash provides consumers with a “bargaining tool.” Its mere existence may allow us to better negotiate compensation for the sharing of our data, in effect allowing us to monetize our (lack of) privacy.

New paper!
Blind Disclosure
Did your school move to P/F grading in the spring? Did you think, “economic theory predicts all students should stick with a letter grade, I wonder if they will?”
Then I have theory, evidence, and a thread for you 1/

The technology that produced the Moderna vaccine started being developed under NIH grants before being spun off into, as it was then capitalized, ModeRNA. NIH doesn't assert a rights to IP funded by its grants, they are open to be commercialized by others. A paper thread 👇👇

A polite, scathing, and comprehensive reply by @jasndoc and coauthors to the "ergodicity economics" of @ole_b_peters.
@NaturePhysics erred in not finding a referee who would ask these basic questions of the authors, but glad a reply is out there.

1/ New paper by @camharvey and me on the editorial process in econ-related fields. We argue against the all-too-common practice of applying the Union Heuristic: requiring authors to perform all requested tests and extensions suggested by referees.

Key findings:
- Academic scientists spend less time analyzing data when there are more people working on the same protein (presumably, in order not to be scooped)
- This is associated with measurably lower quality protein models

@stephaniedcheng looks at the gender gap in biological sciences academia. Bio is one of the most gender equal sciences at undergrad and grad level... The gap emerges for tenure track faculty for women w/ children as women move into jobs which require more standard working hours

@NinaRoussille investigates the "ask gap" in the online labor market Hired.com. She finds that women systematically ask for lower salaries than men, and this leads to a pay gap -- but that a small change in default on the platform can eliminate this pay gap entirely

Novel identification (plausibly random, non-arson building fires lower the cost of new construction) and data (scraped historical rents from Craigslist listings, and individual residents’ address histories) suggest construction improves neighborhoods and LOWERS rents 🏗

A quick thread about current issues around markups. Many people have seen this figure, but there is still a lot of discussion around what it "means". Estimated markups appear to be rising but we aren't really sure why. 1/

History of optimal taxation theory, neatly summarized on one slide.

Etienne Lehmann @EtienneLehmannE
I take the opportunity of posting the slides of my short (9h) course in optimal tax theory for a thread to discuss
What are the most important and policy-relevant principles to learn?
What are the main current limits and the next steps for further research?

Interesting thread 👇.
1. agricultural employment is countercyclical as it absorbs excess labor.
2. small plot holding facilitate the role of the agricultural sector as insurance provider as many people have direct access to land.
3. Land consolidation hence comes at a cost https://t.co/yfHsY77PuG

Sabyasachi Kar @Sabya_K
Thread. Agriculture as shock absorber.
In all the discussions on Indian agriculture and farming, one aspect of this sector gets largely overlooked.
Its role as a social safety net.

Peloton is fascinating for academics.
Why do in person classes? Why have gyms?
It’s hard to build up the motivation to do either, so we usually need an in person coach.
Peloton figured out how to motivate at scale from a distance. Same in education would be a massive shift.

Austen Allred @Austen
As someone who spent years as a missionary I found this notion fascinating, and spent a lot of the night reading about it.
Peloton literally and explicitly set out to create an experience to replicate some aspects of religion.
